What is the C0 property of a weld?

You can visualize C0 as an attachments CFrame like this post below:

Combining Models with respect to their attachment CFrames

Hey There! I’m trying to move one model to another model so that the CFrame of the first Model’s attachment matches the CFrame of the second model’s attachment. (Here I’m moving the red Model with respect to the blue model’s attachment) Before: [image] After: [image] Video To Explain: https://gyazo.com/70ed29211f7b28c71d845cacd8ea1a0f I know how to do this with Position and Orientation values with BaseParts, however I’m not sure how to make this happen for models with CFrame. Thanks f…

Because the math is similar.

Attachment.WorldCFrame = Part0*attachment.CFrame-- find the world CFrame relative to origin axis.
--similar to
OffsetCF = Part0*C0
OffsetCF = Part1*C1
--weld is when the offset CF is the same so
Part0*C0=Part1*C1
